    • Effects of crude oil contaminated sediment on the early life stages of lumpsucker (Cyclopterus lumpus L.). 

      Hustad, Anette (Master thesis; Mastergradsoppgave, 2008-08-15)
      Lumpsucker (Cyclopterus lumpus) is a demersal and shallow water spawning fish species with a relatively long egg incubation period. In case of acute oil pollution the embryos will be exposed to PAHs in the water for a relative long period. In this experiment we made a flow through rock column incubation system with oil contaminated gravel and exposed fertilized lumpsucker eggs to the water soluble ...

    • Inclusion of photoautotrophic cultivated diatom biomass in salmon feed can deter lice

      The aim of this study was to evaluate the potential of diatom (microalgae) biomass as a lice-reducing ingredient in salmon feed. The original hypothesis was based on the fact that polyunsaturated aldehydes (PUAs), e.g. 2-trans, 4-trans decadenial (A3) produced by diatoms can function as grazing deterrents and harm copepod development. Salmon lice (Lepeophtheirus salmonis) is a copepod, and we intended ...

    • Mikroalger i fôr, ny løsning for å redusere lusepåslag på laks – Faglig sluttrapport 

      Hustad, Anette; Vang, Birthe; Eilertsen, Hans Christian; Siikavuopio, Sten Ivar; Sæther, Bjørn-Steinar; Svalheim, Ragnhild Aven; Hansen, Espen Holst; Svenning, Jon Brage; Kousoulaki, Katerina; Whitaker, Ragnhild (Research report; Forskningsrapport, 2020-05)
      I dette prosjektet har vi testet ut en hypotese om at ved å erstatte vegetabilske oljer i fôr til oppdrettslaks med marine oljer, vil man kunne redusere lusepåslag hos laks. Vi har fôret laks med fire ulike fôr, der proteininnholdet er det samme, men oljen er variert. De ulike fôrene vi brukte var kontrollfôr som var standardfôr med vegetabilsk olje, og tre ulike testfôr der vegetabilsk olje ble ...
